Disinsection fungi emulsifiable powder

Abstract

The invention provides a disinsection fungi emulsifiable powder, comprising the following components: disinsection fungi spore powder or mycelium 40-60, vegetable oil 5-15, surfactant 5-10, stabilizer 5-10, dispersant 0.1-1; wherein the disinsection fungi is metarrhizium anisopliae, white muscardine fungi, paecilomyces, hirsutella or the mixture; the surfactant is nonionic surfactant, the vegetable oil is one kind or the mixture of many kinds of the oil according to arbitrary ratios selected from the palm oil, corn oil, soybean oil, cotton seed oil and colza oil; the stabilizer is one kind or the mixture of many kinds of the oil according to arbitrary ratios selected from the xanthan gum, carboxymethyl cellulose, gelatin; the dispersant is DW 1003, glucose ester of fatty acid or the mixture thereof. The storage and transportation of the disinsection fungi emulsifiable powder is convenient and the storage period of the fungi spore is effectively prolonged and the long-term storage is convenient and the preparation activity is higher; after application of the disinsection fungi emulsifiable powder, the oil can effectively absorb the ultraviolet ray and reduce the damage of the ultraviolet ray on the fungi spore, effectively increase the field control-effect stability. The process production technique of the disinsection fungi emulsifiable powder is simple and the disinsection fungi emulsifiable powder is easily mixed with the other compatible synergistic pesticide.

Description

technical field [0001] The invention relates to an insecticidal fungus pesticide, in particular to an insecticidal fungus milkable powder. Background technique [0002] Due to the long-term and large-scale use of chemical pesticides, the ecology has been seriously damaged, the environment has been polluted, and pests have become rampant again. The use of bio-pesticides that do not pollute the environment and are non-toxic to humans and animals to replace chemical pesticides has become one of the important means of integrated pest control. Fungi are the most important group of insecticidal microorganisms. Insecticidal fungi are the only pathogenic microorganisms that have both contact characteristics and prevalence. Their pathogenic mechanisms are complex, and insects are not easy to develop resistance. They have great potential for solving the problem of insecticide resistance in pests. This makes the application of fungal insecticides to control pests widely concerned at h...

Problems solved by technology

Batta (2004) attempted to add spores into water and mix them with emulsifiers to form water-in-oil emulsions. Although the control effect could be increased, the preparations contained water and could not be preserved for a long time. After 10 weeks, the germination rate of spores was reduced to below 80%.
